Re: [ecasound] streaming with ecasound

Hi,

like Sergei noted, you need to make sure all apps use the same audio
format: sample format (int/float, signed/unsigned, bits, endianess, etc),
channels, sampling rate.

So that would be (with lame 3.98 and newer) for instance something
like:

ecasound -f:s16_le,2,44100 -i alsa -o stdout | lame -b 64 -r -S
--signed --bitwidth 16 --little-endian -s 44.1 - - | ezstream ...

... and similar options for ezstream.

Older versions of lame are missing some of the options and you just have
to figure out what it is expected and adjust ecasound accordingly. There's
still no nice option to specify how many channels the input PCM stream has
(you just specify the channel encoding mode with '-m'), but in most cases
the default (stereo) is fine.

All in all, finding the right params might be a bit of a hassle, but
e.g. for white-noise, just adding "-x" to lame options will
probably fix the problem for you (swaps endianess).
